Abstract
Un método implementado por una unidad fronthaul inalámbrica, el método que comprende agregar una pluralidad de primeras señales de canal inalámbrico para producir una primera señal agregada a través de mapeo digital en el dominio de frecuencia (FDM), en donde las primeras señales de canal inalámbrico se colocan en la primera señal agregada en primeras bandas de frecuencia no superpuestas con anchos de banda (BW) de canal sin cambios, convertir la primera señal agregada a una primera señal modulada, y transmitir la primera señal modulada a un enlace fronthaul inalámbrico.
